The steady state ball size distribution in the mill depends on the top-up policy. The effect of the ball size distribution on the milling rate of coal has been measured as a function of ball size distribution. The change in ball size distribution as affected by wear and ball top-up policy has been modelled.
1. Introduction. Mineral crushing is the main source of energy consumption in mineral processing. According to statistics, this consumption accounts for about 35–50% of the total cost of the mine (Curry et al., 2014), or even higher.It may also account for 1.8% of the global electrical energy consumption (Napier-Munn, 2015).More efficient crushing …
